<p>Leaving nominated because I want to at least discuss 1. whether we need/want to collect data on instances of such breakage, and 2. whether we were too aggressive in deciding that going straight to an error without some mitigating mechanism was too aggressive.</p>

<p>but I think I am going to just remove the nomination. this was not such a big deal in the end. The main question I would want resolved is whether we actually documented this breaking change somewhere visible (release notes from release blog post or something similar). But that does not need to be a discussion during the synchronous T-compiler meeting.</p>
